Consider the following class definitions:

class Employee{   private

int empNum;   protected

double empSal;

   public int EmpNum{    

get {return empNum;}    

set {empNum = value;}

}

public double EmpSal {     get

{return empSal;}     set {double

MININUM = 15000;          if

(value

empSal = MININUM;          else

           empSal = value;}

}

public string GetGeeting(){

     string greeting = “Hello, I am employee #” + EmpNum;     

return greeting;

}

} class CommissionEmployee :

Employee{   private double

commissionRate;   public double

CommissionRate{     get { return

commissionRate;}     set {

commissionRate = value;          

empSal = 0;}

}

}

Suppose the following statement is used in a program (client code):

CommissionEmployee salesperson = new CommissionEmployee();

Determine if following statements are valid or invalid. Clearly mark YES or NO. (10 @ 2 each) salesperson = 0.07; salesperson.EmpNum = 345; salesperson.EmpNum; EmpSal = 20000; salesperson.CommissionRate.ToString(“P”);
